Spring MVC，運行時如何從src/main/resources目錄讀取.sql文件？

Question

請幫我解決這個問題。我有一個Hibernate的彈簧MVC項目， 和「src/main/resources /」目錄下的db.sql文件。如何在運行應用程序時在db.sql文件中執行腳本？ 這是我的db.sql文件腳本。

CREATE DATABASE IF NOT EXISTS `accounts`; 
USE `accounts`; 
-- 
-- Table structure for table `role` 
-- 

DROP TABLE IF EXISTS `role`; 
CREATE TABLE `role` (
    `id` INT(11) NOT NULL AUTO_INCREMENT, 
    `name` VARCHAR(45)  DEFAULT NULL, 
    PRIMARY KEY (`id`) 
) 
    ENGINE = InnoDB 
    AUTO_INCREMENT = 2 
    DEFAULT CHARSET = utf8; 

-- 
-- Dumping data for table `role` 
-- 

LOCK TABLES `role` WRITE; 
INSERT INTO `role` VALUES (1, 'ROLE_USER'); 
UNLOCK TABLES; 

-- 
-- Table structure for table `user` 
-- 

DROP TABLE IF EXISTS `user`; 
CREATE TABLE `user` (
    `id`    INT(11) NOT NULL AUTO_INCREMENT, 
    `username`  VARCHAR(255)  DEFAULT NULL, 
    `password`  VARCHAR(255)  DEFAULT NULL, 
    `firstName`  VARCHAR(255)  DEFAULT NULL, 
    `lastName`  VARCHAR(255)  DEFAULT NULL, 
    `email`   VARCHAR(255)  DEFAULT NULL, 
    `dateRegistered` DATE    DEFAULT NULL, 
    `skypeID`  VARCHAR(255)  DEFAULT NULL, 
    PRIMARY KEY (`id`) 
) 
    ENGINE = InnoDB 
    AUTO_INCREMENT = 4 
    DEFAULT CHARSET = utf8; 

-- 
-- Table structure for table `user_role` 
-- 

DROP TABLE IF EXISTS `user_role`; 
CREATE TABLE `user_role` (
    `user_id` INT(11) NOT NULL, 
    `role_id` INT(11) NOT NULL, 
    PRIMARY KEY (`user_id`, `role_id`), 
    KEY `fk_user_role_roleid_idx` (`role_id`), 
    CONSTRAINT `fk_user_role_roleid` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`) 
    ON DELETE CASCADE 
    ON UPDATE CASCADE, 
    CONSTRAINT `fk_user_role_userid` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) 
    ON DELETE CASCADE 
    ON UPDATE CASCADE 
) 
    ENGINE = InnoDB 
    DEFAULT CHARSET = utf8; 


DROP TABLE IF EXISTS `catalog`; 
CREATE TABLE catalog (
    `id`   INT(11)  NOT NULL AUTO_INCREMENT, 
    `user_id` INT(11)  NOT NULL, 
    `link`  VARCHAR(100) NOT NULL, 
    `comment` VARCHAR(100) NOT NULL, 
    `type`  VARCHAR(100) NOT NULL, 
    `insertDate` DATE     DEFAULT NULL, 
    `content` LONGBLOB  NOT NULL, 
    PRIMARY KEY (`id`), 
    CONSTRAINT `fk_catalog` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) 
    ON DELETE CASCADE 
    ON UPDATE CASCADE 
) 
    ENGINE = InnoDB 
    DEFAULT CHARSET = utf8; 

我讀到這一些帖子，我發現有用的結果，例如這一個

Resource resource = applicationContext.getResource("classpath:db.sql"); 
InputStream is = resource.getInputStream(); 

但我不知道如何在我的程序的啓動執行代碼此兩行。 把它放在哪裏。

該問題通過在「HibernateConfiguration.java」中添加此函數來解決。

@Bean 
public DataSourceInitializer dataSourceInitializer() { 
    ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator(); 
    resourceDatabasePopulator.addScript(new ClassPathResource("/data.sql")); 

    DataSourceInitializer dataSourceInitializer = new DataSourceInitializer(); 
    dataSourceInitializer.setDataSource(dataSource()); 
    dataSourceInitializer.setDatabasePopulator(resourceDatabasePopulator); 
    return dataSourceInitializer; 
}
